86161120 ÷ 484 
We want to figure out the number of times 86161120 can be divided by 484.

Step 1:
If we divide 8 by 484, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 484

Moving on to step 2:
The number 484 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 484

Step 3:
If we divide 861 by 484, we get 1 and a remainder of 377.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 484 from 861 to get 377.
Bring next digit (6) of the dividend behind the 377 and repeat the process: 3776 / 484

Step 4:
484 can be fit into 3776 7 times, resulting in a remainder of 388.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 388 after subtracting 3388 from 3776.
Grab the next digit (1) from the dividend, add it to 388, then carry on: 3881 / 484

Advancing to step 5:
3881 divided by 484 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Subtracting 3872 from 3881 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 484

Step 6:
When dividing 91 by 484, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 1780.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 484

Going ahead to step 7:
912 divided by 484 is 1 with a remainder of 428.
Use 1 as the next digit of our solution. 
Result so far: 17801.0
Subtract 484 from 912 to get 428.
Fetch the next digit (0) from the dividend, attach it to 428 and continue: 4280 / 484

Going ahead to step 8:
4280 divided by 484 is 8 with a remainder of 408.
Put 8 as the next digit of the answer. 
Result so far: 178018.0
Subtracting 3872 from 4280 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 9:
4080 divided by 484 is 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 178018.8
If we take 3872 away from 4080, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
The number 484 fits into 2080 4 times, leaving a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 178018.84
If we subtract 1936 from 2080, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
1440 divided by 484 is 2 with a remainder of 472.
Use 2 as the next digit of our solution. 
Result so far: 178018.842
Subtracting 968 from 1440 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 12:
If we divide 4720 by 484, we get 9 and a remainder of 364.
The next digit of our result is 9. 
Result so far: 178018.8429
Subtracting 4356 from 4720 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 13:
3640 divided by 484 is 7 with a remainder of 252.
Write down 7 as next digit of the result. 
Result so far: 178018.84297
Subtract 3388 from 3640 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 14:
When dividing 2520 by 484, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 178018.842975
Subtracting 2420 from 2520 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
When dividing 1000 by 484, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 178018.8429752
If we subtract 968 from 1000, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 484, we get 0 with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 178018.8429752
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 178018.8429752 with a remaining 3.2e-07.
